I hate this so much. Humans are a disease when considering only things like this.<p>What authority does any human have to neuter animals at random? Why? Because they will suffer? The kick them out to the wild if you don't want to see their suffering, let them adapt to there.<p>Few things disgust me more than cruelty disguised as kindness. You can own an animal, you can kill one but only for food or clothing and other survival needs but no one has the right mutilate animals and leave them to linger on.<p>The problem is humans now have weapons, pesticide and tech to fight off things animals would have helped is with and this is our response. You don't need sterlisarion and kill shelters, animals either starve to death or adapt and move out to areas where they can find food/prey. If you are worried about the ecosystem in a city, donate to a zoo so you can look at whatever animals you want, humans and their pets decimating a city's ecosystem is a natural outcome of the human-animal ecosystem!
Our insistence in regulating ecosystems is what is unnatural. Leave the animals be, get comfortable with strays in your city like some cities already are (istanbul and i hear rome too).
